We use a small, glowing rock full of lightning to turn the light reflected off a cat into lightning then send it through the air as invisible waves with the rock to another rock. That rock turns the invisible waves back into lightning, then sends it through a long piece of copper to a huge globe-spanning net of more rocks filled with lightning, more long copper pieces, and long glass pieces. Other people with rocks request the lightning from the net with their rocks via lightning signal. The net then delivers the lightning to the rocks of the other people, and the rock turns the lightning back into the light reflected off the cat.

In historic art pieces depicting multiple humans, there is a law that at least one of those humans will look like they have no clue how or why they got there. It's like Where's Waldo, except instead of looking for Waldo you're looking for the dude that looks like he just dropped acid.
